how to build your own conservatorie base?

Answer 1

If you can lay bricks, then it's easy. Use a string line to mark out the base size. Dig a 600mm wide strip all around, (300mm either side of the string line) and 450mm deep, (at least, or until you reach well compacted sub soil or clay). Pour in 150mm deep concrete strip and leave for a day or two. Lay the cavity wall on the concrete up to DPC height, checking the base is square, (measure corner to corner). Inside the base cover ground with a couple of inch of sand and compact. Use 1200 gauge visqueen, (damp proof) over the whole area. Fill with concrete up to dpc height Let it dry and build up to required finished height. Remember to insulate and use wall ties. You can get insulation for the base from any large diy store. The thicker the better.

Answer 2

1. You can build a concrete slab like the one described in the link below, or

2. You can dig footings the depth required by local regulations. You then can suspend the lumber substructure above the ground on posts and beams that you build. The posts would be directly over the footings. The number of posts and footings would depend on the dimensions of the conservatory and the span limits of the lumber you use. Resting on the posts and beams substructure would be the lumber you would use to create the joists structure that support the sub floor.

Answer 3

same as answer 2 but if you cant lay bricks or blocks buy a brckies mate it will cost you about £30 it's easy to use and will give you the walls you may need cheaper than a bricky. or just lay upto damp then have the frames full hieght from the floor.order frames up after you've got the base done so to get the measurements right
